"Hey, Brother Chen, why are you bringing that up again? You're too vulgar, too direct. How can you suggest that I should use my hands on you again? I've already said that's not happening.
I can accept leaving my 'things' with you, and I've agreed to send you pictures whenever you want, but now your appetite for me just keeps growing. My photos aren't enough for you anymore. I'm really scared that one day, when Zhang Qiang isn't around, you won't be able to hold back and will actually do it with me.
How could a little woman like me possibly resist you?
Brother Chen, I've already said I'd agree to anything, but you absolutely must not have any more extreme thoughts about me, nor should you keep saying such lewd things to provoke me. I'm scared that one day, we won't be able to control ourselves and something reckless happens. I can't be doing these things now.
